Electro-optic characteristics of (001)-oriented Ba0.6Sr0.4TiO3 thin films

Ba 0.6 Sr 0.4 TiO 3 thin films were grown on MgO(001) substrates using pulsed-laser deposition. The films were highly oriented along the (001) direction, and showed a high electro-optic response to an external electric field. The quadratic electro-optic coefficient Rc was 1.0×10−14 m2/V2, and the bi...

Zusammenfassung:Ba 0.6 Sr 0.4 TiO 3 thin films were grown on MgO(001) substrates using pulsed-laser deposition. The films were highly oriented along the (001) direction, and showed a high electro-optic response to an external electric field. The quadratic electro-optic coefficient Rc was 1.0×10−14 m2/V2, and the birefringence variation was as large as 0.09. Various electro-optic applications as well as the microwave applications of barium strontium titanate thin films are expected.
